Use of Technological Tools in the Dissemination of Census Data

Transcription

1 United Nations Regional Seminar on Census Data Dissemination and Spatial Analysis 31 May-3 June 2011, Santiago, Chile Use of Technological Tools in the Dissemination of Census Data Application to CARICOM Region By Edwin St Catherine, Director of Statistics Saint Lucia

2 Context: Censuses in the CARICOM Region are now being conducted 2010 Bahamas, Barbados, Belize, Saint Lucia 2011 Bermuda, Jamaica, Rest of the OECS, Trinidad & Tobago, Suriname 2012 Guyana Beginning of the Census Dissemination Efforts Mostly at the Stage of Planning for Dissemination

3 Outline Technology use to promote the timely release of High Quality Census Data Tools used to Disseminate Census Data Reach the Largest possible audience Enhance flexibility in the Use of Data Use of GIS technologies in Census Data Dissemination Micro Data Dissemination

4 Timely Release of High Quality Census Data Use of image processing software on scanned questionnaires Intelligent Character Recognition (ICR) improves speed of capture Indexing of the images of census questionnaires improves ability to clean data Computer Assisted Coding removes the need for manual coding and speeds up the data capture process

5 Timely Release of High Quality Census Data In CARICOM Region more censuses are being done in 2011 Census is in Process Two additional methods of capture were either tried or experimented with Capture via the use of Handheld computers Jamaica experiment, Grenada small scale implementation

6 Timely Release of High Quality Census Data Remove need for printing and transportation of hardcopy survey forms Remove need for transcribing responses back in office. Automatic branching of questions with consistency checks reduce back-end processing efforts with electronically coded data captured directly in the field

7 Timely Release of High Quality Census Data Limited Online Data Capture Trinidad and Tobago, since we use fairly long and detailed questionnaires requiring special training, this may require further development.

8 Tools used to Disseminate Census Data Traditional Tools Hard Copy Publications CDs and DVDs Static Electronic Media (Static Web Pages, PDF, Excel)

9 Tools used to Disseminate Census Data Emerging Tools Online Queryable Databases Standards Based Tools which facilitate Dissemination (SDMX, DDI etc..) Dynamic Geographic Products Dissemination of Census Micro Datasets Social Media Networking Tools (Twitter, FB Mobile Technologies (SMS, Mobile Apps...

10 Online Queryable Databases Initial deployment of these tools in the 2001 Census and this will again be a means for dissemination of 2010/11 Census CARICOM Region, Belize, Saint Lucia and Trinidad and Tobago, St Vincent and the Grenadines used Redatam+SP Tools, more specifically the Webserver Tools to create this facility with the assistance of CEPAL

11 Online Queryable Databases REDATAM+SP is an interactive system that allows for the on-line processing of any census and other databases sources over the Internet. Data Security of Census Micro-DataSet High Level Language for building customizable interactive webpages Permits in-depth population and demographic analysis at Small Area Level Output, PDF, HTML, EXCEL, Thematic Maps Google Analytics Information on use from within and outside the country of Redatam database

12 Online Queryable Databases

13 Standards Based Tools Standards Based Tools which facilitate Dissemination (SDMX, DDI, etc..) DevInfo/Census Info is especially important for Small Island Developing States since it gives them access to technologies through the use of simple implementation tools, allowing for Organizing, storing and presenting data in a uniform way to facilitate data sharing at the country level across government departments, UN agencies and development partners. Dev Info, Census Info work to maintain and store data in a form which allows for easy exchange and dissemination through the use of standards, such as, SDMX (Statistical Data and Meta Data Exchange) and DDI (Data Documentation Initiative) At the 39th Session of the UN Statistical Commission, attended by delegations from about 130 countries and 40 international agencies, SDMX was recognized as the preferred standard for the exchange and sharing of data and metadata. The Commission also encouraged implementation by national and international statistical organizations.

14 Standards Based Tools CARICOM Region: Training workshop in the use of DEVINFO and CENSUS INFO to assist in the dissemination of Census Data, a number of the CARICOM countries have implementations of Census Info for 2001 done on CD/DVD For 2010/11 Censuses challenge will be to enhance this implementation with online versions of Census Info From CD/DVD Publication to use of Census Info Database running on an SQL Server Backend to allow for user-driven output of Census Data, Indicators and Meta-data, CTTinfo, JAMStats, HelenInfo.

15 Standards Based Tools - IHSN Microdata Management Toolkit A specialized DDI/Dublin Core metadata editor with transformation and cataloguing tools Tools to Create Standard Documentation for Dissemination of Census Data

16 Dynamic Geographic Products Dynamic/Static Geographic Products Online Database dissemination builds in this aspect to a limited extent CensusInfo for Indicators at the Community Level Redatam with Map Generation based on the submission of specific area selections Dissemination of Census Geographic Data in the CARICOM Region Some moves towards the collection of GPS points for buildings and by extension households Opportunity to free the census data dissemination from the basic unit of collection, the EA (Enumeration Area)

17 Dynamic Geographic Products Brazil Example:

18 Dynamic Geographic Products Flexible dissemination of Census Data/Indicators For Blocks, Communities, Streets, Electoral Divisions/Sub-divisions, Planning Areas etc..

19 Dissemination of Micro Datasets The 35th Standing Committee Caribbean Statisticians Adopts the following position: Access to all statistical data, whether microdata or tabular data, shall be strictly in accordance with the Statistics Acts of CARICOM Member States and Associate Members; Encourages Member States and Associate Members to establish mechanisms for disclosure prevention, such as data anonymisation and to provide access to microdata under controlled conditions, such as microdata laboratories; and Encourages international organisations to build capacity at the national level and support the establishment of these mechanisms in CARICOM Member States and Associate Members.

20 Dissemination of Micro Datasets In Pursuit of the Objective of disseminating Micro Datasets within the context of the position adopted by the 35 th SCCS: Work with ECLAC/World Bank on training Caribbean Statisticians in the development of annoymized census datasets. Work with partner agencies (IPMUS) to make available limited Public Use sample data for download from the Internet given the small size of CARICOM Countries

21 Social Media Networking Tools, SMS SMS is an option especially given its wide reach over the cellular network, requires work to push out results SMS have been used to inform the public of need for census, TELCOS donated this service to the Statistics Office in St Lucia Use of SMS can certainly be extended

22 Social Media Networking Tools, SMS Potential Tools for the Dissemination of Census 2010/11/12 Data to be Discussed at RCC Facebook Pages are used to promote participation in the Census Twitter is free compared to SMS, requires payment to TELCOS Twitter Accounts to post on a periodic basis facts of interest to the public about the main results of the Census Statistics Office Twitter Handles will have to be built into web pages of the Offices Twitter Handle Sent via to all major users of Statistics Office Data Users of Twitter clients will see through twitter facts on the Census and links to the results of the census online as they are updated

24 Mobile Dissemination Redatam Census App for Andriod open platform which we could adapt for use at the regional level. CARICOM Level there is the possibility of putting an Android App in Google s Marketplace for higher end professional users in the longer term
